Selenium Use in Auto-Immune Thyroid Disease
Selenium is highly concentrated in the thyroid gland. This trace mineral is a component of enzymes involved in the activation and deactivation of thyroid hormones. A recent review of studies published in 2010 in Thyroid has found selenium supplementation may help those with Hashimoto’s thyroiditis. Patients taking levothyroxin treatment for Hashimoto’s either received 200 mcg of selenium or a placebo for 3 months. Those receiving the selenium experienced a reduction in thyroid autoantibodies, suggesting an improvement in the disease. As a bonus they also reported improvements in well being and mood. The researchers recommend that patients demonstrate improvement in their autoantibodies before continuing with regular supplementation.
